Many weather station guides advise calibrating sensors to nearest stations. This serves well normally unless your location resides in a microclimate(the climate of a confined space or small geographic area). In my case, I see different temps than the local airport due to my microclimate. So adjusting to their location may actually be incorrect. Of course, a good solar shield ensures correct readings, so one must be sure their location temps are highly accurate. I am upgrading my temp shield next week. My solar radiation readings seem to be affected by direct sun exposure. My fairly new Oregon Scientific temp solar shield is terrible. Therefore, upgrade is needed.
